As illustrating'a preferred embodiment of the invention, there, isshown in the drawingsanapparatus intended for choppingmeat, vegetables; and v the'.like;. preliminarytofurther treatment inthe preparation of food, which comprises a supporting frame, consisting of a table. or cowl portion Iii having supporting legs it, braced by crossrods 13. Supported by the frame is adriving' motor I I4 haying an extended armature; shaft l5-to which is keyed a fiber pinion Lain drivingengagementwith a. large gear H carried by and: keyed 1 to a shaft itmounted, in bearings 18 and. 20 carried by the frame or cowl t0. Carried byone side-of the frame is a closed gear caseindicated generally at. having removable cover. plates 25, 26 and 21 to provide accessibility to the various'shaf ts; V j I Rotatably mounted above the cowl is, a. bowl or container 30 adapted to receive the materials to be cut'or treated. The shaft I-8 passes trans verseiy across tlleqmachine and is substantially 25 enclosed withinthe cowl Ill. Shaft l8carries slidably and rotatably mounted: thereon .a worm 3| whichis formed atone end witha clutch member .32adaptedto cooperate with. asecond clutch member 33' pinned to and rotatable with the shaft 18. The worm 3| engageswithanannular gear 35 which is rigidly attached to bowl 35. Cowl i0 is provided with acentral, hub or upstanding boss 31 surrounded by the annular gear 35, which gear has bearing-engagement at 35 upon the cowl to rotatably support bowl '30.

Inorder to facilitate assembly, annular gear 35 is providedv with an; upwardly facing screwthreaded socket) which receives therein an annular screw-threaded ring bolted at 42 to the lower thickened wall portion 43 of bowl. 30. Boss 31 is provided .with a retainer plate; 44 which is bolted thereto by bolts 45, to securely fasten gear. 35 and related parts in place, upon cowl Hi. In assembling, thegear 35, is inserted into position about the hub, 31 and;then the cover 44 is bolted in place on the hub. -Ihean- ,nular. ring 4| is bolted to. the thickened lower wall portion 43 of the container. Of coursathe threaded socket lit-of gear 35, this being easily accomplished by grasping the side of the; bowl],

screw-threaded portion mightbeformed' directly -0 i and turning the bowl. The bowl is screwed down until the shoulder 46 at the lower end of the bowl contacts with a shoulder 41 on the worm gear 35 to hold the parts firmly in place.

The shaft I8 is extended beyond the clutch and bearing 20 as indicated at 50, and a helical gear 5I is keyed to this extended end of the shaft. Cooperating with gear 5I is a second helical gear 52 keyed to a hollow sleeve 53 which is rotatably mounted within an elongated bearing 54 formed by an attachment coupling frame 55 bolted to the frame ID over a side opening 56 therein. The sleeve 53 is provided with a bore 58 which is substantially square in cross section, and is adapted to receive therein in driving engagement a correspondingly shaped end of a driven shaft of an attachment, such as a meat chopper, coffee mill, or the like. The attachment connection is thus in driving, connection with the motor l4 through the shaft I 8 and gears I6'and II. The coupling frame 55 is provided labove'and overhanging the rotatable bowl 30 is offset from the horizontal axis of the bowl (see Fig; 2); and carries at its end food treating means adapted to operate within the bowl, illus trated as cutting knives II The knives thus operate within the curved channel 72 of the .bowl. These knives may be attached to the shaft 66 in any'suitable manner. As shown, the knives are firmly" carried by an integral supporting structure including a sleeve I3 which removably and slidably fits upon an extended end I5 of reduced diameter of shaft 66, and held thereon by anoverlapping shoulder of a set screw I4 received within a threaded bore I6 in the extended shaft end I5. The sleeve I3 is provided with extensions 11 which fit in interlocking driving engagement within cutout grooves I8 in the adjacent portion of larger diameter of the shaft 66. The inner knife member rests against a shoulder "I9 of sleeve I3, while the outer knife member is spaced therefrom by an annular collar-80, the parts being securely held upon the sleeve I3 by a lock nut 8i threaded upon an outer threaded end 82 of the sleeve I3. Removal of set screw I4 permits the sleeve 13 and parts carried thereby to be removed as a unit.

In order to protect an operator from injury during rotation of the cutting knives, a cover 83 is tiltably mounted over the bowl and cutting knives. Cooperating with the tiltable cover 83 is a switch mechanism indicated generally at 84 which is constructed to have interlocking engagement with the cover as a further precaution against possible injury to an operator. illustrated mechanism, a snap switch 85 controls the supply of electrical energy to the motor I4. The'leads 86 and 8'I may be connected to any suitable source of electrical energy, such as the ordinary house lighting line through a fuse and. switch box (not shown). From the switch mechanism 84 leads are carried in a closed conduit 88 to the motor I4. An interlock bar 89 is provided with a manual control pin 90 for sliding the bar 89 from the position shown in Fig. l in which it overlaps a portion of the cover 83 and prevents In the raising of the cover, to a position to the left when it engages the snap switch 85 to prevent the switch from being turned on. With the parts in the position shown in Fig. l, the interlock bar cannot be pushed to the left until the switch 85 is moved to stop the motor I4, and thus the cover cannot be tilted to permit access to bowl 30 until after the motor I 4 and driven parts have been stopped. With the interlock bar 89 moved to the left, the motor cannot be started; so that the cover must be lowered back into place and the interlock bar. 89 moved to the right before the machine can be put in operation.

The cover 83 is mounted on a bracket carried by the frame Ill. The mounting is constructed to permit removal of the cover to facilitate cleaning of the apparatus; and as a further protective feature is 50 arranged that the cover can be removed only after it has been tilted back to permit access to the container. As shown more particularly in Figs. 4, 5 and 10, an upstanding bracket 9I is bolted to cowl I9 by bolts 92. The upper end of the bracket is formed with spaced arcuate shaped portions or guides 93 and 94. The bracket is also provided with a bore 95 within which is pressed a pin 97, the ends of which protrude beyond the bore as indicated at 98. The pin 9'1 is fixedly secured within the bore by a set screw 99.

The cover 33 has spaced depending socket members I98 and ifllnesting within the guides 33 and 94. Both socket members are identical in construction except for being faced in opposite directions. Each is formed by a depend ing lug integral with the cover 83, which lug has a bore E83 therethrough. Mounted in this bore is the hub $04 of a circular plate 165. The huh I {it is provided with a screw-threaded bore within which is threaded a bolt Hi6 having a washer I 05 to clamp plate I55 in place. provided at the end opposite the hub with an enlarged bore or circular opening IQ! of a diameter slightly larger than the diameter of the protruding end 98 of pin 97 which is received therein, and also with a radial slot its extending outwardly from the bore Kill. A dowel pin I09 is provided to locate the plate I05 with the slot I68 in proper position.

As shown more clearly in Fig. 5, which corresponds to the position of the cover in closed or normal operating position, the slots IE8 then 6X tend generally in a horizontal direction and the upper ends of the upwardly facing arcuate guides 93 and 94 prevent the cover from moving horizontally such as is necessary to enable the en s 98 of the pin 9'! to pass through the slots 38, The arcuate shaped guides permit removal of the cover only in a general upward direction. When the cover is tilted upon its pivotal support on the pin 9'! through an angle of approximately 90, the slots I88 will then extend vertically and face -downwardly. In this position, the cover maybe lifted upwardly, the ends 98 of pin 9'! passing through the slots I08.

Carried by the cover 83 and slidable in guides H0 is a knife cleaner II! which comprises a rectangular plate having two spaced slots indicated at H2 through which the blades of the cutting knives II pass upon rotation thereof. This knife cleaner is clamped in position upon the cover 83 by a hand screw H4 which is threadedly mounted in a lateral extensie. H3 of cover 83. The end of screw I I4 is pointed and is adapted to seat in a groove I I5 of knife cleaner III, a portion of the cleaner II I being broken away and in section in Fig. 5 to illustrate the construction. Thecleaner H! is-provided with an-upstandingst'op I it adapted to contact with the end of lateral extension H3 to limit the inward movement of the cleaner I I1 In assembling, withscrew l Min raised positiomthe cleaner i l inserted and slidinwardly alongguides Hi until stop Ht contactslthe end ofilateral extension H3, when groove H5 will then be accurately centered with the axisof screw I'M which is then,

tightened to firmly clamp the cleaner in operating position. The bracket 91 is provided with a stop H9 against which a part carried by cover 83 is adapted to contact when'the cover is tilted to open position, inorder to limit the tilting n'ioveinent of the cover.

Thorough lubrication of the movable parts is provided and at the same time these parts vLand the motor .are protected from-injury and the ingross of water, so that the machine may be readily washeddown with a hose or the like to permit easy and rapid cleaning; As shown the motor 14, which is preferably provided with a housing substantially enclcsing the motor, is in position beneath the cowl it of the frame and between the legs l'i thereof. The motoristhus protected :from washing water directed downwardly upon the bowl and cowl, and is positioned within the horizontal confines of the frame, whereby injury due to exposure or protruding parts is avoided.

At the sametime; theflocr space required by the machine is considerably reduced.- Thus in a machine of the character-illustrated, having a bowl diameter of approximately twenty-one inches and capable of handling a :large amount'of foodstuffs,

the overall length and "width of the machine is,

only about twenty-nine inches, While the overall height is less than four feet; The intermeshing gears forminga driving connection between the extended armature shaft of the motor and the a bowl and food treating shafts are enclosedwithin the side gear casing 25. to :provide. for adequate lubrication supplied by the grease cup orpressure lubricant connection lZfi-and the protection from washing water. This positive gear drive overcomes the inherent objections of belt or chain drives, while affording a compact arrangement with. few parts. At the same timeaconvenient gear ratio is providedby the'intermeshing of the large gear i! with the small pinion 65 to drive shaft SG at the properhigh speed; and by the intermeshing of motor pinion I6 with largegear H to drive bowl shaft l8 ata slower speed. The

rotativespeed of the bowl is further stepped sage l2! extending transversely across "the machine, within which the shaft IS :ismounted to seal this shaft and provide an enclosurefor the reception of lubricant. The bearing I9 ofishaft i8 and the interior space surrounding'this shaft is supplied'with lubricant from a pressure lubricant connection H2. The cowl is formed with a depending pocket i23 for the bowl mounting. This forms an oil reservoir I24 about 'theannular worm gear 35 and the worm 3|. Shaft 18 extends through its enclosing casing,.as indicatedformed in extension iii.

ingress of water from the outside into the 'bear Lin'Fig. 3 at .125, into'the oil reservoir I24 opposite the-gear 35 to provide for the'intermeshing or gear-s31 and 35. The bowl 39 is provided with a'depending annular lip. E25, and the cowl Id is provided with a cooperating upstanding flange 121, servingto prevent leakage'of water into the oil reservoir i261. The extending end Fifi of shaft 18 and the attachment connection including the 1 intermeshing gears 55 and .52 are confined within a hollow enclosure E28 to which lubricant is supplied by connection 29.

The hollow frame extension Hi forms a stationary support for the knife shaft 68 so that this shaft and its bearings need not bemoved or disturbed during the normal operation of the 'machine, and at the same time provides an enclosing structureforiniug a lubricant reservoir E39 about theshaf t, which is supplied with lubricant from 'a suitable connection not shown. The reservoir. 13% is closed at one end by a retaining ring l3! holding the bearing in place, the ring'having alternate projections and grooves cooperating withthe shaft 6'5; The reservoir is closed'atthe other end by a'retaining ring Hi2 holdingbearing G8 in place. In order to prevent leakage of lubricant and contamination of food stuffs in the bowl, ring 232 is provided with an oil feed back arrangement, comprising an annular groove 133 formed in this ring about the shaft and a channel 534 connecting this groove'to the periphery of I the ring at its inner end where the oil can pass back into the reservoir I313 through a groove 134 In order to prevent the ing and oil reservoir, the ring 232 is'also provided with a water feed back arrangement comprising an annular groove 35 on the outer side of groove i533 and a channel .635 connecting this groove to the exterior of the outer end of the ring.

In order to clear the overhanging frame extension'ltl, the tiltable cover is terminated at one side as indicated at ltl". IA stationarycover por tion I38 is provided beneath the frame extension 'lllzcomplementary to the .tiltable cover 33 to=cover Cover portion :38. is

this portion of bowl 3%. provided with an upstanding flange $39 which snugly fitsalong one side of frame extension if;

and is bolted thereto as indicated at Mil to hold the cover portion securely in place. 'I'iltable cover-8M5 formed with'an upstanding portionl l l which receives the rotatingknives, and-asemicircular hub portion I62 which receives and looselyfits over the extended end'of the frame exten sion 10. The construction is preferably such that thecoverii?v rests as indicated at M3 upon the 2' smooth flattened peripheral lip of bowl 3t to prevent the escape of foodstuffs from the bowl.

Cover portion B38 is likewise arranged to have a sliding andsealing engagement with the-lip of the bowl, andcarries a baflie HM to direct foodstuffs back into the chz-mnelv Z2 of the/bowl to be again acted upon by the knives. Bothcovers +terminate short of one side of the bowl that an open space Hi5 provided through which an operator may "watch the progress: of the. cutting operation. The upstanding portion iii is curved downwardly at ll? almost intoengagement with the bottom of the bowl sothat the lr'nives are effectively enclosed, and an operator may insert his'hand into the space M5 to remove foodstuffs 'during'operationbf the device withoutdangeroi injury; In' actual :practice, such motor driven food handling machines are operated upon different .sources of supply of electrical energy in different localities, and upon electrical energy of varying characteristics. Thus some localities are supplied with SO-cycle alternating current, while other localities are supplied with 50, 40, 30, 25, or other cycle current. It is found that with apparatus of this character, the most elfective results are obtained when the cutting knives are driven at a high speed within a certain high speed. range, and the bowl is rotated at a slow speed within a certain slow speed range, and the ratio of the speed of the cutting knives to the speed of rotation of the bowl is maintained within a certain speed ratio range, whereby the bowl rotates through only a very slight angle for each rotation of the knives so that the knives cut thin slices of the material being treated. Thus very effective results are secured in a machine of the character and size above described with a knife speed of substantially 1750 R. P. M.; and a bowl speed of substantially 10 R. P. M., giving a speed ratio of 175 to 1. It is also desirable from the standpoint of economy to provide constant speed motors, such as induction type A. C. motors, as the power means.

The present invention provides a standard construction of machine which may have a constant speed motor, and in which the proper speeds of rotation of the cutting knives and the bowl as well as the proper speed ratio therebetween may be readily obtained irrespective of varying frequencies encountered. As shown, the machine is provided with a standard size construction of frame, bowl, cutter shaft and driving mechanism including gears i! and 65 which provides for a constant speed ratio between the rotative speeds of the knives and bowl. Associated with this standard arrangement is a unitary motor assembly comprising the driving motor I4 having an extended armature shaft with interchangeable pinion I6, the motor and pinion being also detachable as a unit. Thus if a 50-cycle current is encountered instead of a 60.-cycle current, a larger size pinion may quickly and easily replace a 60- cycle pinion to secure the desired speeds and speed ratios.

In order to provide for the proper meshing of interchangeable pinions of various sizes, the motor I4 is suspended from the lower portion of the cowl I9 by'means of an interchangeable mounting or booster block I 46 which is removably fastened to the motor housing by bolts I41 and is removably fastened to the bottom of the cowl I by bolts I48. Thus as standard equipment with the interchangeable pinions for the electrical circuits of various frequencies, a number of different booster blocks I46 may be provided, which booster blocks are of varying sizes in order to support the motor with the center line of the armature shaft at different elevations so that the varying diameter pinions may properly mesh with the gear I'I. Thus the standard machine can be adapted to the varying frequency conditions encountered, or can be converted to desired speeds very easily and quickly.

In order to permit the unitary motor assembly to be removed from or assembled on the machine without disassembly of the parts, the rear of the gear case 24 is provided with an opening I49 closed by a removable cover. plate I50 .bolted thereto by bolts II. The removable cover plate I50 is more particularly illustrated in Fig. 7. As shown, the plate is provided with a circular opening I 52 adapted to snugly receive the extended end I53 of the motor housing, to close thegear case 24. The construction of the plate I50 shown in full lines is for a 60-cyc1e four-pole A. C. motor or a 30-cycle two-pole A. C. motor. The construction is such that the proper position of the opening I52 in the plate I50 for a 50-cycle fourpole A. C. motor or a 25-cycle two-pole A. C. motor, in order to obtain, the proper speed and speed ratios with an interchangeable pinion I6 of the proper size, is indicated in dotted lines at I52. The opening I49 and plate I50 may be constructed of such size that the center indicated at I54 of the circular opening I 52 is located the same distance below the horizontal diameter of the plate I50 as the center I54 of the circular opening I52 is located above the horizontal diameter of the plate. Therefore a plate suitable for 60- cycle four-pole and 30-cycle two-pole motors may be used for 50-cycle four-pole and 25-cycle twopole motors by merely turning the plate through an angle of 130 degrees so that the opening is moved from the position shown in full lines to the position shown in dotted lines, whereby a single plate is suitable for all four frequencies. To take care of other frequencies, different interchangeable plates having properly positioned openings therein are provided. By removing the bolts I48 'and the bolts I 5| the motor I l with extended armature shaft I5 and pinion I6 together with thecover plate I55 and the booster block I46 may be removed and replaced as a unit.

The machine is equipped as above described with an attachment connection whereby various power driven attachments such as meat choppers, coffee mills, and the like may be used with the machine, the motor I4 and driving interconnections being used to operate the power driven attachments. In order to protect the operator from injury and to reduce the power consumption when an attachment is used, means are provided for stopping operation of the bowl 30. This is accomplished by the provision of the worm 3I which is mounted for axial sliding movement on shaft I8 and the clutch 32-33. In the position shown in Fig. 3, the clutch members are in engagement, and as clutch member 33 is keyed to shaft I8 the worm 3| is positively rotated during rotation of shaft I8 to thereby rotate the worm gear 35 and bowl 3!). The normal direction of rotation of bowl 30, when driven by the motor during operation, is counter-clockwise as shown by the arrow in Fig. 2, so that the thrust produced by the intermeshing of gear 35 with worm 3| tends to hold the clutch members 32--33 in engagement. When it is desired to disengage the clutch members 3233 to stop rotation of the bowl 30, this may be accomplished by grasping the bowl 30 and turning it in a counter-clockwise direction faster than its speed of rotation, which serves through the intermeshing gears 35 and M to slide the worm 3| to the left along the shaft I4 to remove the clutch member 32 from the clutch member 33 while maintaining the worm 3I in mesh with the worm gear 35.

The clutch member 32 is provided with a plurality of grooves or slots IBil about its periphery into which a spring pressed ball I6I is adapted to fall when the worm 3I is slid to its disengaged position to thereby hold the worm in this disengaged position, and permit shaft I 8 to freely rotate within the worm. The attachment connection may then be driven through shaft I 8 and hollow sleeve 53 without rotation of the bowl. When it is again desired to provide a driving connection between shaft I8 and bowl 30, the bowl is turned clockwise as shown in Figs. 2 and 3 to overcome the restraining action of spring-pressed of sleeve r63 to-oontact with, theboss let to look I 8-,to' re-engasethe clutchmembers 32:43.. Ad.-

the parts in adjusted position. "The lower: end, of sleeve 1-63 is provided with any intur'ned lip l6] of such diameter as, to, prevent, the ball #52 from passing therethrough. The construction is such that when the, Worm is C11 is engagement with shaft ta through the clutbhmerhbers 32-33, he ball; l-iil: is heldout' of contact with the surface of the worm, but when the worm is in its,-.,disensaeed positionlthe ball sets within one of the slotsv to lock the worm in this position.

In Fig. 6 is shown a slightly modified form in which means are provided for stopping operation of the cutter shaft and cutting knives car-- ried thereby, or for stopping rotation of the bowl, or both, when the attachment connection is to be used. Ihe machine is identical in contsruction with that previously described, except that in addition the; pinion 6'5 is slidably mounted upon but keyed to the shaft 65 carried in bearings, one of which is indicated at fit, in the frame extension it of the gear case 2 1. The gear 65 is provided with a suitable manipulating button no whereby it may be slid along the extended end Hi of shaft 66 from the disengaged position as shown in full lines in Fig. 6 to the engaged position .as shown in dotted lines when it meshes with the large gear ll. Thus by sliding the gear 65' to disengaged position, and by grasping the bowl and turning it to disengage the worm clutch, the operation of both the cutting knives and the bowl may be stopped, so that the attachment connection can be used with a minimum of danger to the operator and a minimum of expenditure of power.
